Supply power using the car's cigarette lighter (12V), convenient to carry, does not occupy much space, and is clever and practical; With it, you can inflate your car anywhere and anytime.

Usage Method:
Insert the rubber hose tip into the tire valve, and when you hear the tire deflating sound, it indicates that air is flowing. Immediately clamp the valve wrench into the valve at a 90-degree angle inward, and at this point, the air will stop leaking.
Remove the plug, connect the cigarette lighter.
Turn on the motor to begin the air filling process.
When inflated, the instrument pointer begins to rise with the increasing air pressure. When the large pointer reaches the appropriate tire pressure for the car (generally 193-241KPa for car tires), remove the plug and the air nozzle.

Notes:
The machine is not suitable for large trucks.
When using, you should start the car engine.
If the air pressure rises rapidly within a short period of time (rising to 689KPa in three seconds), it indicates that the air pressure is blocked, and air is not entering the tire. Immediately turn off the power and remove the air valve, then re-operate.
Infuse continuously every 10 minutes, and it's best to take a break;
Only for 12V cigarette lighter power input.
